Background The Patient‐Rated Wrist Evaluation (PRWE) is a patient‐reported questionnaire focusing on symptoms and function in wrist pathologies. It consists of 15 questions regarding pain and functional activities of the wrist. Rheumatoid arthritis (RA) is a multi‐systemic disease characterized by inflammation of the wrist and hand joints in almost all patients. This study aims to test the validity of PRWE in patients with RA. Method Seventy‐five patients with RA from a single outpatient clinic participated in the study. Patients filled out the Michigan Hand Outcomes Questionnaire (MHOQ) and grip strength of both hands were measured. Patients filled out the PRWE questionnaire consecutively once for the dominant and once for the non‐dominant hand. Correlations between PRWE and MHOQ and grip strength scores were analyzed by Spearman's correlation method. Results Our results demonstrated that there was a very strong correlation between the PRWE and the MHOQ and a moderate correlation between the PRWE and grip strength ( P < .001). PRWE also showed negative and fair correlation with grip strength of both hands ( P < .001). Conclusions The Patient‐Rated Wrist Evaluation is a valid tool for evaluating wrist involvement in patients with RA. PRWE may be preferred in the busy clinical setting since it has simple and short questions. Additionally, it may provide a sensitive follow‐up tool for patients separately using its subscales of pain and function.
